    摘要: A method of manufacturing a solar cell includes the steps of: providing a substrate having a front side, a back side and a doped region; forming a conductor layer on the front side; firing the conductor layer at a temperature such that the conductor layer is formed with a first portion embedded into the doped region and a second portion other than the first portion; forming an anti-reflection coating (ARC) layer on the front side and the second portion, wherein the ARC layer covers the conductor layer so that the second portion of the conductor layer is disposed in the ARC layer; and removing the ARC layer on the conductor layer so that the conductor layer has an exposed surface exposed out of the ARC layer, wherein the exposed surface of the conductor layer is substantially flush with a first exposed surface of the ARC layer.

    摘要: A method of manufacturing a solar cell comprises the steps of: forming a lower conductor layer on a front side of a substrate; firing the lower conductor layer at a first temperature to form a first portion embedded into a doped region of the substrate and a second portion; forming an anti-reflection coating (ARC) layer on the front side and the second portion, wherein the ARC layer covers the lower conductor layer such that the second portion is disposed in the ARC layer; forming an upper conductor layer, corresponding to the lower conductor layer and electrically connected to the lower conductor layer, on the ARC layer; and firing the upper conductor layer at a second temperature to form a first portion embedded into the ARC layer and a second portion, which is exposed out of the ARC layer.
